ROCK-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 238,676, dated March 8,1881.

Application filed November 20, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. GoLDING, of Chicago, in the county of (lookand State of Illinois, have invented a new and valuable Improvement inRock-Crushers; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a perspective view. Figs. 2 and 3 aredetails.

& This invention relates to crushers for rocks,

The invention consists in the construction hereinafter described.

In the drawings hereto annexed, A represents a frame consisting ofhead-blocks B B and central bearing-blocks, G G, tied together andbraced by rods D.

J ournaled in bearings 01 d in bearing-blocks O O is a shaft, E, havingmiddle portion, 6, cam-shaped.

Just inside of bearings O G are risers F F, through whose lower holes,ff, passes shaft E, its body portion 6 resting in said holes, which arecircular. Near the top of these risers are arranged on a line twoelongated holes, f f, elongated transverse the risers.

H H represent the crushingjaws, whose rear ends, a a, rest on ledges bb, upon the inside of head-blocks B B. The faces of these jaws arecorrugated, as shown at c.

I I represent studs, projecting from the sides of jaws H H at theirfront ends, said studs bearing in elongated holes f f.

K represents a wheel to which power is to be applied.

As wheel K and shaft E revolve, the cam e, turning in circular holes ffof risers F F, causes said risers to move up and down, and, by means ofthe elongated holes f f and the studs on jaws H H bearing therein, saidjaws are caused to vibrate, and their corrugated faces coming togetherwill crush anything thrown in between.

The employmentof two segments with curved crushing-faces, either plainor corrugated, in connection with a mechanism for imparting to the samean oscillating motion, is not new. Segment-cams, a crank-shaft, and ayoke arranged together to produce a differential movement of the cams isalso old in rock-breakers, and protection is only asked herein for theconstruction shown, described, and hereinafter claimed.

What I claim is The combination of jaws H H, having studs I I, risers FF, having elongated holes f f and circular hole f, and shaft E, havingcamshaped portion 0, the whole arranged together and in a suitableframe, as and for the purposes described.

In testimony' that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
